Are Hummers ideal for driving in snow? You bet they are. But Hummers have limitations, despite their immense traction and huge bulk. So you need to be careful with the way you handle them in the white stuff.
We’ve researched this topic and provide you all the details about making it through the snow in your Hummer.
Are Hummers good in snow?
Hummers handle snow very well. But you need to have the right snow tires, enough ground clearance, and some driving experience when you drive a Hummer on snowy or icy roads.
There is a huge misconception about the capabilities of a Hummer while in the snow. All Hummers, including the smallest H3s, are excellent for off-raiding.
Because of their weight, Hummers can churn through deep amounts of snow which smaller vehicles will find impassable. But much depends on the driver’s experience and the tires on the truck.
To stay out of trouble, learn to gauge snow depth before attempting to drive your Hummer through it.
Even if you have a Hummer H1, it’s dangerous to drive through snow of 3 to 4 feet; although you will hear people say they do.
In reality, you may not make it through 3 feet of snow for a long distance in your Hummer.
7 Factors That Impacts How Hummers Handle Snow
The snow depth a Hummer can handle depends on a lot of factors including:
1) The Snow Type
There are different snow types if you plan to go out during the winter.
The road condition is different when driving on fresh snow, lightly fallen, crusty, wet, hardpack, spring snow, drift snow and weeks-old snow.
Your Hummer being a hulk of a truck can thrash through fresh, lightly fallen snow but you will require more torque and traction to push through hardpack, especially if it is above two feet.
It is difficult to gauge snow depth except you have a tape.
To be on the safe side, keep your snow driving to 2 feet even if you have the best tires and enough ground clearance.
2) Ground Clearance
Hummers have 16″ of ground clearance, which is ideal for fording streams and plowing through snow. But the clearance is relative.
To avoid getting stuck in snow, it’s important for your differentials to be out of the white stuff.
The differentials allow the Hummer to transfer torque to individual wheels so you don’t get bogged down.
The differentials work with the help of fluids. Snow and ice can interfere with their operation.
You want to make sure the snow is not too high to put your ground clearance at a disadvantage.
Too high snow can make it difficult to back out even when the differentials are engaged in low lock. Without enough ground clearance, it becomes difficult to build momentum.
And you risk damaging your windshield as your tires throw up large amounts of snow.
A rule of thumb to gauge the snow depth your Hummer can drive through is to check whether it reaches your brush guard.
If the snow is that high, you probably have no business driving in that condition because it is not safe.
3) Appropriate Tires
If you live in snow country, get a decent set of winter tires for your Hummer.
The stock tires that come with your truck are excellent on the road and the trails, but they are not ideal for winter driving.
The best winter tires have a narrow design with deep treads. Narrow tires allow the truck to gain traction by cutting through the ice.
A misconception with snow tires is that they need to be wide so you can float. The thinking is that you should deflate your tires for floatation’s sake.
But a Hummer is not a Corolla and driving in quicksand and mud is way different from snowy conditions.
Your Hummer won’t float if you deflate its tires. it will only find it harder to cut through the white stuff because of the vehicle’s weight.
Hummer owners have reported Swampers as one of the best snow tires out there.
Their narrow form reduces the surface area the tires have to push against. And they are taller at 38″, which increases clearance.
4) Qualities of a Good Winter Tire
Winter tires should have sipes, i.e., treads with deep grooves and cuts to provide improved traction in the snow.
The tread blocks are also smaller, allowing the tire to cut into the snow or ice more easily. This promotes traction, handling, and braking.
Many users report 43-46 psi as the ideal tire pressure when driving their Hummers in snow.
You want your snow tires to drain snow away from the treads so they don’t harden and become ice. And they should deflect snow away from the Hummer’s frame.
5) When To Get Snow Tires
Hummers have one of the best 4WD and traction control systems in the world, but these driving aids are as good as your tires.
If winter temperature regularly falls below 45 degrees Fahrenheit in your area, you are better off getting four high-quality winter tires for your Hummer.
Swap the winter tires with your stock wheels during the colder months when the roads have foot-deep blankets of the white stuff for improved traction, braking and cornering capability.
While Hummers have more contact with the ground because of their weight, they can also be difficult to stop, especially if your tires perform poorly on snow.
This makes it even more important to get snow shoes for your truck to reduce the chances of dangerous skidding.
If you intend to use stock tires for driving in snow, consider getting chains for improved traction.
Many people don’t like tire chains, but a lot of drivers admit they are very effective and have been their saving grace in dire situations.
6) The Hummer Model
Hummers are not equal. When driving in snow, the wagon variants fair better.
This is because the extra weight at the rear provides more contact with the solid ground below the snow, improving stability.
The vehicle’s weight is also an important factor when driving in snow.
The H1s, which are the heaviest Hummers, can handle the toughest amount of snow but even the H3 with its sub 5000-pound bulk can hold its own.
The only advantage the wagons have is that their heavier rear allows you to build momentum because the drive tires start rolling first, making it easier to free yourself of the snow.
7) Driving Technique
When driving in snow, keep things at a slow and leisurely pace.
Despite the Hummer’s exceptional performance in all conditions, braking can be difficult if the road is covered with hard pack snow or ice.
You might own the H1 with the legendary Torsen II traction system or Detroit locks, but these won’t help if your 3-ton truck is skidding uncontrollably.
Remember your stopping distance is a function of your GVR and the amount of grip on your tires. So keep things really slow.
It doesn’t matter if you are late to your destination, so long as you arrive safely.
What to Do When Your Hummer Is Stuck in Snow?
When driving your Hummer during the summer, keep the tires well inflated for improved ground clearance and traction. And make sure you have winter tires.
If you get stuck, try these tips:
Clear a Path for Your Tires
Create a path for your vehicle before starting the engine.
Clear a path in the front, rear and underneath the Hummer’s rear wheels.
You want your tires to move a few feet to the front and back to gather momentum.
Check that snow does not block the exhaust pipe before starting the vehicle. Many people have suffered carbon monoxide poisoning because of a clogged tailpipe.
Remember to bring your snow equipment such as a snow shovel in case you need to dig your way out. Your equipment may also come handy if you encounter people who forgot to go out prepared for the weather.
Turn Off Traction Control
The Hummer’s traction control can be a huge limitation during winter conditions. Traction control sends the highest amount of torque to the tires that have traction.
But to get unstuck, you need both wheel drives, i.e., your rear tires to have traction. To get a better control of the truck, turn off the traction stability control.
You can also make it through the snow with 4 low locked. Note that when you use 4 low or let up the throttle when your tires slip, the Hummer disengages traction control.
Rock Yourself Out
Use the forward-and-back technique.
Straighten the wheel, put the vehicle in the lowest gear and move forward a bit. Then back up slowly without revving the engine. Stop and apply some gas in the forward motion.
This back and forth can loosen the snow and provide the traction to help you break free.
It can also wreck your transmission. Try to apply the brake or shift to neutral before transiting from drive to reverse and vice versa.
Avoid spinning the tires so you don’t cause damage to the treads, your windshield and nearby vehicles.
If you still can’t lose the snow, especially if the tires spin uncontrollably, try improving traction.
Apply sand, rocks, cardboard or kitty litter in front and behind the drive tires.
Avoid using salt because it can cause your vehicle to rust and is not that effective in temperatures below 25 degrees Fahrenheit.
Antifreeze is even worse as it is toxic and can contaminate water bodies used for drinking.
In dire cases, you can even use plywood, leaves, weeds, branches and even your Hummer’s floor mats to increase traction. Be careful not to injure yourself or damage your tires.
It’s important to keep a cool head while trying to get unstuck in snow. Don’t hit the gas hard and drive as slow as required to maintain momentum.
Remember, it’s momentum you need not speed to get out of the white stuff.
If your vehicle slides, get off the accelerator to get its direction. If you think the vehicle is going out of control, apply a bit of gas to direct the tires to a safe position.
Can You Mount a Plow on a Hummer?
Yes, the H1 and H2 are ideal for mounting a snowplow. The H3 should also be able to use a plow, but you won’t find many companies making them.
However, you are better off buying an old 4×4 truck for your snow plowing needs.
The Hummer is big and powerful enough to handle the task, but why use an expensive truck for such hard work? It’s not worth it.
Hummers are excellent vehicles on solid ground and in the snow.
But to get optimal winter performance from your H1 or H2, try investing in quality snow tires. And learn the proper techniques for driving in winter.
The most important point is to drive slowly and keep your cool. Don’t forget to keep your winter equipment in the hood and keep tire chains somewhere in case you need them.
Remember the weight of your vehicle and the state of its tires determines your braking distance.
So take it slow on the white stuff!
